资 源 简 介
spawn is a simple parallel execution utility written to appeal to the
Unix mindset.
spawn reads shell command lines from stdin, one per line, and then
executes them as maximum of N child processes in parallel, and waits
for all of the children to exit.
If a child process fails with a non-zero exit code, no new children
are spawned. Then spawn waits for all existing children to exit and
returns the failed exit code.
I wrote ``spawn"" to scratch my own itch because I didn"t find anything simple and purposeful to do the job.
